Dear @chbartist sir!
The rising sun is always saluted, so the owner of the company told that passive and jealous manager that if you can do something better then do not sit quietly otherwise.The subject matter that we do not have knowledge about, it is proper to remain calm.There are always some mischievous elements in society whose sole purpose is to count the weaknesses of others and to humiliate the other.Positive thinking and loyalty to your actions always leads to the path of progress towards humans.The only reason for the company's owner to reach the top was that he always gave such a person a place in his company who is active and who has passion for duty.
The lack of activity snatches the identity of the person, blocking the path of success. That is why we should be vigilant in our subject area and complete our work with complete dedication.
Regards.
